We haven't lost, yet.
At the least, I will still fight the good fight for property rights to exist.
It is important to note that you will have to fight so called conservatives in the battle to retain your rights.
Prpoery rigths exist. Its the owners of the property that are requesting their rights be subject to a smoking ban. Thses bans are being done using due process. This is not a property rights issue. It may be a due process issue, but property rights can be impaired so long as a due process is followed.
I have said before that I believe that in the case of a restuarant owner who was allowed smoking and where a town disallow it they have effectively taken his property and the owner has the right to compensation but the remedy is still not to allow smoking. Further, in the case of a regional wide ban I cannot see how an owner could prove lost of income unless he is at the border of the regional ban.
